The present invention generally relates to poultry chillers for reducing the temperature of whole birds after the birds have been eviscerated on a poultry processing line. More particularly, the invention relates to a hanger bearing assembly configured to support an auger within the poultry chiller.
It is desirable to reduce the temperature of chickens and other type poultry after the birds have been processed, or de-feathered, eviscerated, and are otherwise oven-ready and before the birds are packaged for delivery to the retail customer. A conventional poultry chiller 10, as shown in
As noted, chilled water is added to the tank 12 at the outlet end 16 of the tank 12, where the birds have been chilled and are being lifted out of the tank 12. The water flows against the birds in the opposite direction of movement of the birds, thereby assuring that the birds are always flowing into the cleanest water and that there is always a temperature drop between the temperature of each bird and the temperature of the water about each bird. Typical trough-shaped tanks 12 of the chillers 10 can be 5 to 12 feet in diameter and 15 to 150 feet in length. Frequently, one or more hanger bearings 30 are provided to assist in properly supporting the auger 20. Typically, the maximum space between hanger bearings 30 is approximately 35 feet.
As best seen in
One of the problems of existing hanger bearings 30 is that the interruption of the helical blade structure at the intermediate bearing location impedes the forward movement of birds through the poultry chiller. Also, it is possible that some birds will move backwards in the chiller due to the counter flow of water once a bird passes by the trailing edge of a segment of the helical flight structure. Those birds that move backwards about a segment of the helical flight structure require more time than is intended to move from the inlet end to the outlet end of the trough because they traverse the same segment of the chiller more than once. The reverse movement of these birds tends to create, or increase, the size of product surges traveling through the poultry chiller. The surges result in uneven unloading of the birds at the outlet end of the chiller, causing personnel handling the birds at the outlet end of the chiller to either speed up or slow down depending upon the output of birds from the chiller. In some cases, surges can require the addition of extra handling personnel. In those instances where personnel are not available, it is not uncommon for the birds to back up in the chiller discharge chute, causing birds to spill over the sides of the chute and handling tables positioned at the outlet end of the chiller. It is possible to collect these birds prior to spill over and place them in suitable vats and storage containers. However, for those plants that do not have additional handling personnel, or that don't respond quickly enough to the surges, the birds will frequently fall to the plant floor, leading to lost product and unsanitary conditions.
Another problem with typical hanger bearings is that the relatively large spacing required between independent segments of the helical flight structure (approximately 10 inches and up) allows birds to remain in the poultry chiller after processing is complete. These birds must be removed by handling personnel prior to cleaning the poultry chiller. Removal of the stranded birds increases the time required to clean the poultry chiller, thereby increasing the down time for cleaning the chiller. As such, fewer birds can be processed through the chiller for each production run. In addition to increased time and expense associated with the clean-up process, expense is incurred due to loss of product at the hanger bearing. Longer chillers require more hanger bearings to support the auger, thereby resulting in more frequent surging and increase product loss.
From the foregoing, it can be appreciated that it would be desirable to have a hanger bearing assembly for use with a poultry chiller that permits minimum horizontal displacement between segments of the helical flight structure. As well, it would be desirable if the hanger bearing assembly permitted spacing between the segments of the helical flight structure such that birds were prevented from moving through the chiller counter to their intended direction. Thus, a heretofore unaddressed need exists in the industry to address the aforementioned deficiencies and inadequacies.
Briefly described, this invention involves a poultry chiller that includes hanger bearing assemblies for use in supporting a segmented auger of an auger type poultry chiller. The hanger bearing assembly allows smaller gaps to be formed between the segments of the auger. This reduces the tendency of birds moving through the poultry chiller in a direction counter to that intended. An embodiment of the hanger bearing assembly for use in an auger type poultry chiller has an auger with a first flight and a second flight both secured to an auger shaft, the first auger flight having a first flange plate and the second flight having a second flange plate. A bearing disk is secured between the first flange plate and the second flange plate. A bearing block is disposed about the bearing disk, a lower bearing plate is secured to the poultry chiller, and the lower bearing plate has a support segment configured to receive the bearing block. An upper bearing plate is configured to receive the bearing block. The upper bearing plate is secured to the lower bearing plate, thereby maintaining the bearing block adjacent the bearing disk and securing the auger to the lower bearing plate.
Other systems, methods, features, and advantages of the present hanger bearing assembly will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the hanger bearing assembly, and be protected by the accompanying claims.
The hanger bearing assembly can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the hanger bearing assembly. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Reference will now be made in detail to the description of the hanger bearing assembly as illustrated in the drawings. While the hanger bearing assembly will be described in connection with these drawings, there is no intent to limit the hanger bearing assembly to the embodiment or embodiments disclosed therein. On the contrary, the intent is to cover all alternatives, modifications, and equivalents included within the spirit and scope of the hanger bearing assembly as defined by the appended claims.
Referring now in more detail to the drawings, in which like numerals indicate like parts throughout the several views,
The auger 110 is positioned longitudinally in the tank 102. An electric motor or other conventional power means (not shown) is provided to rotate the auger 110. The auger 110 includes an auger shaft 112 and a helical blade structure formed around the shaft 112. As shown in

Referring back to
Preferred embodiments of the present hanger bearing assembly 140 can include bearing disks 150 having widths of approximately two inches and lower bearing plates 142 and upper bearing plates 144 having widths of approximately one inch. Although these dimensions have been determined to provide an adequate area of contact between the bearing disk 150 and the bearing block 160, embodiments are envisioned wherein these dimensions vary significantly. For example, these dimensions are influenced by the weight of the auger 110 that each bearing assembly 140 is required to support. Also note, as the diameter of the bearing disk 150 increases, a constant amount of contact area can be maintained although the width of the bearing disk 150 is reduced in the longitudinal direction. Reduced bearing disk 150 width translates into reduced longitudinal spacing between the first and second flight segments 120, 122.
